San Francisco continues to work on solidifying its rotation even after re-signing Tim Lincecum and adding Tim Hudson, with Henry Schulman of the San Francisco Chroniclereporting that the Giants are “working toward” a deal to bring back right-hander Ryan Vogelsong.

Vogelsong became a free agent after the Giants declined his $6.5 million option for 2014 following a rough year in which he posted a 5.73 ERA in 19 starts at age 35. His strikeout rate took a nosedive, his average fastball velocity fell below 90 miles per hour, and Vogelsong’s secondary numbers weren’t a whole lot more promising than his ugly ERA.

Still, as a potential fifth starter in a rotation led by Madison Bumgarner, Matt Cain, Hudson, and Lincecum he’d be a reasonable enough re-sign on a modest one-year contract.
